Lessons in how to restore a wetland ecosystem

Restoration, unlike landscaping, should rely on natural processes to take the lead as soon as possible, after the initial interventions are completed. The restoration of geophysical and hydrologic conditions should be our first goal, followed by controlling invasions and trials of biotic interventions.

In this post David Moreno Mateos discusses his paper ‘Ecosystem response to interventions: lessons from restored and created wetland ecosystems

After over 30 years and billions of dollars (and euros, pounds, and yuans) of restoring wetlands globally, and especially in the USA, the time has come to evaluate the results, and particularly to find out how wetlands are responding to our efforts. The results found in this paper show that once the hydrology is restored the effect of revegetating is unclear, and in some instances is even negative.

What this could mean is that wetlands need us to restore them in the best possible way with our present knowledge of their hydrological dynamics, that is, their connection with the water-table, the tides, or the stream flow, or the basin that allows the water to stay for longer or shorter periods. But beyond that, it seems that wetlands will…
